CS263456B1 - Device for narrowing time intervals measuring - Google Patents

Abstract

Reaction belongs to radio measuring techniques The device comprises a forming circuit and a first channel signal and a forming circuit the second channel signal, the forming circuit time intervals attached to the first input of the selector connected to the counter impulses. The pulse counter is connected through the averaging block with the indication block. The device includes a carrier generator and a noise generator coupled in accordance to the first and second phase modulator inputs, associated with the first forming circuit impulses. Carrier frequency generator it is also connected to a second forming a pulse circuit whose output is connected to the second input of the selector. At the same time it has device two blocks of time connection connected in accordance with the forming circuit a first channel signal and a forming circuit second channel signal. Block Outputs time connections are associated with the forming the time interval and the second the timeslot block inputs are connected to the first pulse shaping circuit.
